I’m using jquery address plugin , I have implemented the plugin on a listing page , when I click on one of the links , the function will pull the data using ajax and get the content and overwrite the current list html , this page has ‘back’ button , I use window.history.back() to go back to the listing page , this work fine until this point , but after that when I click again on one of the links again , the jq address behavior is lost .
the open_ajax function used to pull the data and inserted in paginatedContent html div
$(document).ready(function(){
refreshjQAddress();
});
function refreshjQAddress(){
mainPath = "";
if($('.jqaddress').length > 0){
$.address.init(function(event) {
$('.jqaddress').address(function() {
return $(this).attr('href');
});
}).internalChange('change', function(event) {
path = event.value;
var ran=Math.random();
urlPath = path;
console.log(urlPath);
alert(urlPath);
open_ajax(urlPath);
mainPath = urlPath;
}).externalChange(function(event) {
var windowLoc = window.location+"";
hashIndex = windowLoc.indexOf("#");
if(hashIndex > 0){
newLoc = windowLoc.substring(hashIndex+1);
mainLoc = windowLoc.substring(0,hashIndex);
if(mainLoc.indexOf("http://") > -1){
mainLoc = mainLoc.replace("http://","");
indexOf = mainLoc.indexOf("/");
mainLoc = mainLoc.substring(indexOf);
}
mainPath = mainLoc;
windowLoc = newLoc;
}
if(mainPath == ""){
mainPath = windowLoc;
}
if(windowLoc != mainPath){
var ran=Math.random();
open_ajax(windowLoc);
}
}).history(true);
}
}
var oldData;
function open_ajax(path){
var ran=Math.random();
if(path.indexOf("?") > 0){

I am using a handlebars template to stick some info on my nav bar. The info is coming from a Rails controller via an AJAX call. The AJAX, given that it's asynchronous, is finishing after the template has received it's variables, thus a variable that should be set in the AJAX call never does so. Here's the code:
export default {
name: "data-menu-item",
initialize: function(container) {
$(document).ready(function() {
var source = $("#notification-menu-item").html();
var template = Handlebars.compile(source);
var user = Discourse.User.current();
var pro = false;
var logged_user = false;
var data_url = "";
$.ajax("/custom_group_names", {
type: 'GET'
}).done(function(res){
if(res.custom_group_names){
console.log(res.group_names);
for (var i=0; i < res.group_names.length; i++) {
// Agents, Brokers, ManagingBrokers, MortageBrokers, admins
if (res.group_names[i]["name"] === "Brokers" || res.group_names[i]["name"] === "ManagingBrokers" || res.group_names[i]["name"] === "MortageBrokers") {
console.log("groups were brokers, etc.");
pro = true;
data_url = "twobydev.com/brokerdashboard";
} else if (res.group_names[i]["name"] === "admins" || res.group_names[i]["name"] === "Agents") {
console.log("groups were admin or agents");
pro = true;
data_url = "twobydev.com/agentdashboard";
console.log(pro);
console.log(data_url);
}
}
}
});
if(user) {
logged_user = true;
if(user.total_unread_notifications > 0) {
new_notification_class = "new-notifications"
notification_count = "(" + user.total_unread_notifications + ")";
}
}
var html = template({pro: pro, logged_user: logged_user, data_url: data_url});
$('body').prepend(html);
});
}
}
logged_user gets set because it is outside of the ajax call, however, I need pro and data_url to be set as well. Any advice or help is much appreciated!
Move the template processing into the ajax callback
function processTemplate(){
var html = template({pro: pro, logged_user: logged_user, data_url: data_url});
$('body').prepend(html);
}
$.ajax({
.....
}).done(function(res){
/* existing processing code */
// now process template
processTemplate()
});
You just need to move this...
if(user) {
logged_user = true;
if(user.total_unread_notifications > 0) {
new_notification_class = "new-notifications"
notification_count = "(" + user.total_unread_notifications + ")";
}
}
var html = template({pro: pro, logged_user: logged_user, data_url: data_url});
$('body').prepend(html);
inside of your done function.
I'm trying to add an "onclick" event with their respective function from js JQuery to an interactive table td I'm doing in another .php file, the problem is not executed in the place where I want to do it but if the same instruction is executed correctly within an AJAX request a few lines below, will show you the code:
This instruction is giving me the problem:
$(td).attr("onclick","agregar_pensum_etapa2 (this,'"+subject+"','"+level+"','"+stage+"');");
And this, the function I want to run with the "onclick"

I try this:
$(td).click(function(){
$(td).attr("onclick","agregar_pensum_etapa2 (this,'"+subject+"','"+level+ "','"+stage+"');");
});
And in the html it prints correctly but does not work, like he was not the "onclick" there. And the function if it works, I put the onclick to that function when I load the page and if it works, but when I click the td and give back to click to restore does not restore the onclick.
Instead of setting the onclick attribute, why not do use .click() again with closures? So your code would be something like...
$(td).click(function(){
var td = this;
$(td).click(function () {
agregar_pensum_etapa2(td,subject,level,stage);
});
});
Do you write
$(Document)
Instead of $(document) with small letter "d".
I use prettyPhoto version: 3.1.6 to display simple lightbox with thumbnail.
Normally title attribute appear inside the lightbox for the active/selected image.
My client ask for this change
http://i.stack.imgur.com/7932x.jpg
How I can accomplish this?
Here is a part of my code
<a rel="prettyPhoto[pp_gal]"href="1.jpg" title="Staring at the sun"><img src="2.jpg"></a>
try this jquery function. You may have to style it a little.
(function($)
{
$.fn.avia_activate_lightbox = function(variables)
{
var defaults =

};
var options = $.extend(defaults, variables);
var imagedefaults =
{
autolinkImages: 'img[title!=""]'
};
return this.each(function()
{
var elements = $(options.autolinkElements, this),

I don't have all that much experience with Prototype and I've been working with jQuery to get things working properly on our site found here. Today I've added a jQuery based script for session handling. The problem I'm having is that even though I've gotten so far today in terms of functionality, I can't seem to get the change event fired via jQuery.
I'm using the following code currently, but it isn't working properly (you can test it on the site.. as soon as you change the year using your mouse, the AJAX is triggered and a Make can be selected)...
var yearSelected = jQuery.jStorage.get("yearSelected");
console.log(yearSelected);
// Set the vars...
if ((jQuery("div.amfinder-horizontal td:nth-child(1) select").val() == "0")) {
jQuery("div.amfinder-horizontal td:nth-child(1) select option").each(function() { this.selected = (this.text == "2003"); });
jQuery("div.amfinder-horizontal td:nth-child(1) select").trigger('change');
console.log('Set the year!');
}
The following code is the Prototype script controlling this and I need to fire off the change event, and would love to do it via jQuery if at all possible.
var amFinder = new Class.create();
amFinder.prototype = {
initialize: function(containerId, ajaxUrl, loadingText, isNeedLast, autoSubmit)
{
this.containerId = containerId;
this.ajaxUrl = ajaxUrl;
this.autoSubmit = Number(autoSubmit);
this.loadingText = loadingText;
this.isNeedLast = Number(isNeedLast);
this.selects = new Array();
//possible bug if select order in the HTML will be different
$$('#' + this.containerId + ' select').each(function(select){
select.observe('change', this.onChange.bindAsEventListener(this));
this.selects[this.selects.length] = select;
}.bind(this));
},
onChange: function(event)
{
var select = Event.element(event);
var parentId = select.value;
var dropdownId = 0;
/* should load next element's options only if current is not the last one */
for (var i = 0; i < this.selects.length; i++){
if (this.selects[i].id == select.id && i != this.selects.length-1){
var selectToReload = this.selects[i + 1];
if (selectToReload){
dropdownId = selectToReload.id.substr(selectToReload.id.search('--') + 2);
}
break;
}
}
this.clearAllBelow(select);
if (0 != parentId && dropdownId){
var postData = 'dropdown_id=' + dropdownId + '&parent_id=' + parentId;
new Ajax.Request(this.ajaxUrl, {
method: 'post',
postBody : postData,
evalJSON : 'force',
onLoading: function(){
this.showLoading(selectToReload);
}.bind(this),
onSuccess: function(transport) {
if (transport.responseJSON){
this.clearSelectOptions(selectToReload);
var itemsFound = false;
transport.responseJSON.each(function(item){
itemsFound = true;
var option = document.createElement('option');
option.value = item.value;
option.text = item.label;
option.label = item.label;
$(selectToReload).appendChild(option);
});
if (itemsFound){
$(selectToReload).disabled = false;
}
}
}.bind(this)
});
}
},
isLast: function(select)
{
return (this.selects[this.selects.length-1].id == select.id);
},
isFirst: function(select)
{
return (this.selects[0].id == select.id);
},
clearSelectOptions: function(select)
{
$(select).descendants().each(function(option){
option.remove();
});
},
clearAllBelow: function(select)
{
var startClearing = false;
for (var i = 0; i < this.selects.length; i++){
if (startClearing){
this.clearSelectOptions(this.selects[i]);
$(this.selects[i]).disabled = true;
}
if (this.selects[i].id == select.id){
startClearing = true;
}
}
var type = (((this.isLast(select) && !this.isNeedLast) && select.value > 0) || ((this.isNeedLast) && ((select.value > 0) || (!this.isFirst(select))))) ? 'block' : 'none';
if ('block' == type && this.autoSubmit && this.isLast(select))
{
$$('#' + this.containerId + ' .amfinder-buttons button')[0].form.submit();
} else {
$$('#' + this.containerId + ' .amfinder-buttons')[0].style.display = type;
}
},
showLoading: function(selectToReload)
{
var option = document.createElement('option');
option.value = 0;
option.text = this.loadingText;
option.label = this.loadingText;
$(selectToReload).appendChild(option);
},
};
I had the same problem. Here is solution. When you create : amfinder-horizontal the html goes something like this
<div class="amfinder-horizontal" id="amfinder_5333ffb212b09Container">
...
</div>
Look at id element : amfinder_5333ffb212b09 Container, bold part is also the name of variable that is amfinder object (created from prototype). It's a random name. This is from the extension source :
<?php $finderId = 'amfinder_' . uniqid(); ?>
...
<script type="text/javascript">
var <?php echo $finderId ?> = new amFinder(
'<?php echo $finderId ?>Container',
'<?php echo $this->getAjaxUrl() ?>',
'<?php echo $this->__('Loading...')?>',
'<?php echo Mage::getStoreConfig('amfinder/general/partial_search')?>',
<?php echo intval(Mage::getStoreConfig('amfinder/general/auto_submit')) ?>
);
</script>
So on every page refresh there is different name. var <?php echo $finderId ?>
Steps :
// Find the name for amfinder object.
var objName = jQuery("div.amfinder-horizontal").attr('id').replace('Container','');
// set Value to that select - copied from your code
jQuery("div.amfinder-horizontal td:nth-child(1) select option").each(function() { this.selected = (this.text == "2003"); });
// call the change event of that object
var targetObj = {
target : jQuery("div.amfinder-horizontal td:nth-child(1) select")[0]
};
window[objName].onChange(targetObj);
I have the following javascript code having class named as PurchaseHistory.
var baseUrl = null;
var parameters = null;
var currentPageNumber = null;
var TotalPages = null;
var PageSize = null;
$(document).ready(function () {
baseUrl = "http://localhost/API/service.svc/GetOrderHistory";
parameters = '{"userId":1 , "page":1 ,"pageSize":4}';
currentPageNumber = 1;
var history = new PurchaseHistory();
history.ajaxCall(parameters);
});
function PurchaseHistory() {
/* On ajax error show error message
-------------------------------------------------*/
this.onAjaxError = function() {
$('#error').text('No internet connection.').css('color', 'red');
}
/* Ajax call
-------------------------------------------------*/
this.ajaxCall = function (parameters) {
$.support.core = true;
$.ajax({
type: "POST",
url: baseUrl,
data: parameters,
//dataType: 'json',
contentType: "application/json; charset=UTF-8",
error: function () { this.onAjaxError() }
}).done(function (data) {
var json = data.GetOrderHistoryResult;
var jsonObject = $.parseJSON(json);
var history = new PurchaseHistory();
history.populateOrderHistory(jsonObject);
TotalPages = jsonObject.PgCnt;
currentPageNumber = jsonObject.CrntPg;
});
}
this.populateOrderHistory = function(results) {
var rowOutput = "";
var his = new PurchaseHistory();
for (var i = 0; i < results.Results.length; i++) {
rowOutput += this.renderCartList(results.Results[i], 1);
}
}
this.renderCartList = function(res, i) {
var container = $('#prototype-listelement>li').clone();
container.find('.order-date').text(res.OdrDate);
container.find('.item-count').text(res.Qty);
container.find('.total').text(res.Amt);
container.find('.order-id').text(res.OdrId);
$('#mainul').append(container).listview('refresh');
}
this.loadNextPage = function () {
parameters = '{"userId":1 , "page":' + currentPageNumber + 1 + ',"pageSize":4}';
this.ajaxCall(parameters);
}
}
The ajaxCall is made on the ready function of the javascript.
This ajax calls returns Json object with pages information, which includes current page number, total pages and page size.
Currently I am able to display the information on the UI, when the page gets loaded.
My Issue:-
I want to call the ajax method again, on the button click event.
How this can be made possible and where can I store the information obtained from previous ajax call?
For pagination I would create a link that will load more items onto the page, and save a starting number to pass to your data layer. This example loads 20 at a time.
<a class="more" href="#" data-start="0">show more</a>
$("a.more").click(function(e){
e.preventDefault();
var start = $(this).attr('data-start');
$.get('/more-data, { start: start }, function(d){
var next = start+20;
$("a.more").attr('data-start', next);
//process results here, do something with 'd'
});
});
